Q 11 :    

Energy released when two deuterons $\left({}_1{\mathrm{H}}^2\right)$ fuse to form a helium nucleus $\left({}_2{\mathrm{He}}^4\right)$ is:             

(Given: Binding energy per nucleon of ${}_1{\mathrm{H}}^2=1.1 \text{MeV}$ and binding energy per nucleon of ${}_2{\mathrm{He}}^4=7.0 \text{MeV}$)                [2025]

• 8.1 MeV

   

• 5.9 MeV

   

• 23.6 MeV

   

• 26.8 MeV
